INNERSOLE r011 sHons.

Specification of Letters ratent. Patented Feb. 16, 1915 Application filed. November 1'8, 1 913. Serial No. 801,731.

To all whom it may concern:

Be it known that I, WILLIAM J. MACFAR- LAND, a citizen of the United States of America, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Innersoles for Shoes, of W'hICl'I thG following is a specification.

This invention relates to inner soles for fered off from the channel on the outm'de to a. thin edge on the inner side. v

Theinvention further consists in certain novel features of construction and arrangement of parts which will be fully understood lay-reference to the description of the drawingsand to the claims hereinafter given;

Of the drawings: Figure 1 represents a I plan of an inner sole embodying the principles of the present invention. Fig. 2 represents an inverted plan of the same. Fig. 3 represents an elevation of the same in position to be placed on a last. Fig. 4 represents a section through the fore part, the cutting plane being on line 4-4on Fig. 2, and Fig. 5 represents a section through the shank part, the cutting plane being on line 5-5 on Fig. 2.

Similar characters designate like parts throughout the several figures of the drawln s.

Tn the drawings, 10 is the inner sole having formed on its under face the rib 11 extending from the front of the shank 12 on the inside around the toe to the heel seat 13. Between the heel seat 13 and the end 14 of the rib 11 the shank is chamfered off from the channel 15 on the outside of the shank to nearly a feather edge on the inside thereof. The purpose of this chamfcring oil of the shank on the inside is to Lqive this portion of the inner sole great flexibility so that 2 of the drawings with the heel part 13 in the position shown in dotted lines. Afterthe blank has been cut and its shank cham fered oil as indicated in Fig. 5, the

/fore part is secured to a last and then the heel part is sprung into the position shown in full lines in Fig. 2 and the thinner por tion of the shank is Worked down into the hollow formed in the shank of the last. If the inner sole while in this position is/secured to a shoe a high yielding arch will be formed at the shank which is adapted to support the arch of the foot and will buckle upwardly with every forwardstep taken by th wearer of the shoe.

By this construction the arch is permanently supported when support is most needed, that is, during walking and running. The springing of the blank into the shape shown in the accompanying drawings may be accomplished during the construction of the shoeor prior thereto as desired.

It is obvious that the'rib l1 vvill'stitien the outside of the shank so that the flexible arched portion 16 will be on the inside of the shank and conform to the arch of the foot of the person Wearing the shoe, the springin of the inner sole being in accord ance witi certain well-defined rinciples of manufacturing shoes on'scienti 0 lines.

By the use of an inner sole constructed as shown and described a shoe may be made Without the usual metal shank support and a natural support given to the arch of the wearers foot which will yield when necessary during the various movements of the foot.

It is believed that the many advantages of this invention will be fully understood from the foregoing description.

Having'thus described my invention, I claim:

1. An inner sole pro ided with a channel in its under face along the outer edge of its shank portion and having the under face of the shank portion chainfered oil from said channel to a thin inner edge, the heel portion of said sole being otlset from the fore part and adapted to be moved laterally in the manufacture of the shoe, thereby forcing the cliain'l ercd otf portion of the shank upwardly and forming a high yielding arch on the inside of the shank.

2. A n inner sole having the under face of its shank chamfered off at the inside and its Signed by me at 4 Post Ofhee Sq, Boston, heel portion formed offset relative to the Mass this 13th. day of November, 1913.
